Does a Google Map element have to be in the DOM when instantiating?

问题

I am instantiating a Google Map object like so:

this.map = new google.maps.Map(this.el, {
    center: new google.maps.LatLng(this.lat, this.lng),
    mapTypeId: google.maps.MapTypeId.ROADMAP,
    zoom: this.zoom
});

Where this.el is an object created via document.createElement('div') but has not yet been inserted into the DOM. When I later append this.el to the DOM I get a map that looks like this (note all the weird gray space):

I do not have this problem, though, if I first append this.el to the DOM and then instantiate the map object. Is there a way to create the map and then append it? This would greatly simplify some of my map code (I am using this in Backbone.js views).

Thanks.

After you append this.el to the DOM, you have to call google.maps.event.trigger(this.map, 'resize');
